3 Claims.

This invention relates to spouts and, more par ticularly, to a sealedcontainer spout.

In the past leakage has occurred from the/top of the spout on acontainer containing a-liquid during shipment of said container, orbefore it was desired to use the contents of the container, through thecap on said spout becoming loose or through the failure to properlytighten the cap. Prior seals for spouts were not only difiioult to breakbut broke in such a manner as to injure the spout so that a cap couldnot be replaced tightly thereon, which caused leakage of the contents ofthe container.

It is an object of the present invention to provide a sealed containerspout which seal may easily be removed when it is desired to use thecontents of the container.

Another object of this invention is to provide an elongated containerneck or spout adapted to receive a removable closure cap, with a sealwhich may be removed cleanly from the spout without injury thereto, sothat the closure may be replaced tightly thereon and there will be noleakage.

A further object of this invention is to provide 'a seal for a containerspout adapted to receive a cap, which seal is broken and removed fromthe spout when the cap is removed.

Other objects will be obvious or will appear during the course of thefollowing specification.

In accomplishing the objects of the present invention it has been foundmost satisfactory to provide a container spout having a head on the topthereof formed by an annular groove in the body of the spout said spouthaving a passage therein extending from the base thereof to a'pointadjacent said annular groove, the

head acting as a seal for said passage. The spout is constructed toreceive a screw cap on top thereof said cap having a recess thereinadapted to receive the head of the spout, the cap and the head of thespout both being of compressible metal, so that by compressing the topof the cap from opposite sides thereof, after it is positioned on thespout, sufliciently to also compress the head, unscrewing of the capwill twist the head from the spout unsealing the passage therein thehead being removed as the cap is unscrewed.

The invention will appear more clearly from the followingdetailed-description when taken in connection "with the accompanyingdrawing, showing by way of example an embodiment of the invention,together with a possible modification thereof.

In the drawing:

Figure l is an elevational view of the spout oi the present inventionwith the cap positioned thereon;

s Figure 2 is an. elevational view of the spout with the cap removedtherefrom;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2;

Figure 4 is a plan view taken on the line A i of Figure 1;

Figure 5 is an elevational view, showing the removal of the seal fromthe spout;

Figure 6 is an elevational view with the cap positioned on the spout,the opposite sides of the cap being compressed;

Figure l is a view similarto figure 6, showing the cap removed from thespout; and

Figure 8 is a plan view taken on the line 8-43 of Figure 6.

Like numerals refer to like parts throughout the several views.

The container spout of this invention comprises a body portion it,having a skirt M which may be of any well-known form, the body portionit being preferably tapered from the skirt ill toward the top of thespout. The body portion it may be in. the form of an elongated neck of acontainer, formed integrally with the top thereof, if so desired.

While the spout may be of any desired compressible material, it ispreferably made of white metal. In the form of the invention shown inFigures 1 through 5, inclusive, the spout need not be of a compressiblematerial, since, as will hereinafter appear, it is not necessary tocompress the same.

At the top of the spout is a head l2 formed on said spout by an annulargroove l3 the groove is, in turn, forms a neck M. The neck M is 40tapered upwardly toward the head I2, the deepest portion of the groovebeing adjacent the body Ill. The body portion I0 adjacent the neck I4 isbevelled, as shown at I 5. Screw threads iii are formed in the bodyportion Ill. The body portion 10 is adapted to receive on the screwthreads IS a cap l1. Extending through the body In and into the neck I4is a passage Ina.

When it is desired to remove the head l3, which head acts as a seal onthe passage Illa, it is mere- 60 ly necessary to apply a lateralpressure to the head l2, which will cause the same to become detachedfrom the body portion [0, at the bottom of the neck [4 where the neck isof smallest diameter. (See Fig. 5.)

As shown inFigure '7 of the drawing, the cap I! has a recess I8 in thetop thereof to receive the head It; The cap is also tapered at l9 so asto fit the bevel 15 on the body portion [0.

The cap, the body portion and the head of the spout, as illustrated inFigures 6, 7 and -8 are of a compressible material. After the cap ,"isplaced upon the body portion [0, as shown in Figure l, the oppositesides thereof adjacent the top may be compressed as, for example, with amachine, pliers, or any other desired means, forming compressed portions20 and 2| on opposite sides of the cap. The cap is compressed to such anextent that the head l2 within the recess I8 is also compressed on theopposite sides thereof, as shown in section in Figure '7.

When it is desired to use the contents of a container having a spout ofthis invention, the sides of the cap of which have been compressed afterthe cap has been placed upon the spout, it is merely necessary tounscrew the cap l1. Unscrewing of the cap will twist the head l2 and theneck I! thereon from the body portion Ill and remove the same as the capis removed from the spout, unsealing the passage Illa. The twist actionwhen the cap is unscrewed will give a head and neck were merely pulledupwardly from said body portion. A clean break is very essential, sincethe user, after breaking the seal, will desire to Place the cap back onthe spout after use. A clean break will allow the cap to be firmlyrepositioned on the spout by screwing the same down tightly until thetaper IS in the cap I! firmly engages the taper I on the bottom portion.

It is apparent that the specific illustrations shown have been given byway of illustration and not by way of limitation and that the structureabove described is subject to a wide variation and modification withoutdeparting from the scope or intent of the invention, all of whichvariations and modifications are to be included within the scope of thepresent invention.

What is claimed is:

1. A container closure comprising an elongated neck having a bodyportion screw-threaded to receive a cap thereon, a cap of compressiblematerial adapted to be screwed onto andofi of said neck, a head ofcompressible material formed on said body portion and projecting intosaid cap, a reduced neck between said body portion and said head formedby an annular groove in said body, said neck having a passage thereinextending through the body portion to the reduced neck thereon, the headand reduced neck acting as a seal for said passage, and compressedportions formed in the opposite sides of said cap and the sides of saidhead adjacent thereto when said cap is in position on said spout,whereby unscrewing of said cap from said spout causes the head and thereduced neck to be twisted and removed from said body portion.

2. A container closure comprising a spout having a body portionscrew-threaded to receive a cap thereon, a cap of compressible materialadapted to be screwed onto and oil of said spout, a head of compressiblematerial formed on said body portion and projecting into said cap, aneck between said body portion and said head formed by an annular groovein said body said groove being of greatest depth adjacent the body andtapered toward said head, said spout having a passage therein extendingthrough the body portion to the neck thereon the head and neck acting asa seal for said passage, and compressed portions formed in the oppositesides or said cap and the sides of said head adjacent thereto when saidcap is in position on said spout, whereby unscrewing of said cap fromsaid spout causes the head and the neck to be twisted and removed" fromsaid body portion.

3. A container closure comprising a spout having a body portionscrew-threaded to receive a cap thereon, a head of compressible materialformed on said body, a neck betweensaid body portion and said headformed by an annular groove in said body said groove being of greatestdepth adjacent the body and tapered toward said head, said spout havinga passage therein extending through the body portion to the neck thereonthe head and neck acting as a seal for said assage, a bevel on said bodyportion adjacent to and tapered toward said groove, a cap ofcompressible material adapted to be screwed onto and on" of said spoutsaid cap having a taper therein adapted to engage the bevel on said bodyportion, and a recess therein to receive said head, and compressedportions formed in the opposite sides of said cap and the sides of saidhead adjacent thereto when said cap is in position on said spout,whereby unscrewing of said cap from said spout causes the head and theneck to be twisted and removed from said body portion.
